107
6.14.2 Security
The following screen appears when Wireless Security is selected. The options shown
here allow you to configure security features of the wireless LAN interface.
Click Apply/Save to implement new configuration settings.
WIRELESS SECURITY
Setup requires that the user configure these settings using the Web User Interface
(see the table below).
Select SSID
Select the wireless network name from the drop-down box. SSID stands for Service
Set Identifier. All stations must be configured with the correct SSID to access the
WLAN. If the SSID does not match, that client will not be
g
ranted access.
Network Authentication
This option specifies whether a network key is used for authentication to the
wireless network. If network authentication is set to Open, then no authentication
is provided. Despite this, the identity of the client is still verified.
Each authentication type has its own settings. For example, selecting 802.1X
authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP
Encryption will also be enabled as shown below.
108
The settings for WPA authentication are shown below.
The settings for WPA-PSK authentication are shown next.
109
WEP Encryption
This option specifies whether data sent over the network is encrypted. The same
network key is used for data encryption and network authentication. Four network
keys can be defined although only one can be used at any one time. Use the Current
Network Key list box to select the appropriate network key.
Security options include authentication and encryption services based on the wired
equivalent privacy (WEP) algorithm. WEP is a set of security services used to
protect 802.11 networks from unauthorized access, such as eavesdropping; in this
case, the capture of wireless network traffic.
When data encryption is enabled, secret shared encryption keys are generated and
used by the source station and the destination station to alter frame bits, thus
avoiding disclosure to eavesdroppers.
Under shared key authentication, each wireless station is assumed to have received
a secret shared key over a secure channel that is independent from the 802.11
wireless network communications channel.
Encryption Stren
g
th
This drop-down list box will display when WEP Encryption is enabled. The key
strength is proportional to the number of binary bits comprising the key. This
means that keys with a greater number of bits have a greater degree of security and
are considerably more difficult to crack. Encryption strength can be set to either
64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10
hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26
hexadecimal numbers. Each key contains a 24-bit header (an initiation vector)
which enables parallel decodin
g
of multiple streams of encrypted data.

115
Field Description
Fragmentation
Threshold
A threshold, specified in bytes, that determines whether
packets will be fragmented and at what size. On an
802.11 WLAN, packets that exceed the fragmentation
threshold are fragmented, i.e., split into, smaller units
suitable for the circuit size. Packets smaller than the
specified fragmentation threshold value are not
fragmented. Enter a value between 256 and 2346. If you
experience a high packet error rate, try to slightly increase
your Fragmentation Threshold. The value should remain
at its default setting of 2346. Setting the Fragmentation
Threshold too low may result in poor performance.
RTS Threshold Request to Send, when set in bytes, specifies the packet
size beyond which the WLAN Card invokes its RTS/CTS
mechanism. Packets that exceed the specified RTS
threshold trigger the RTS/CTS mechanism. The NIC
transmits smaller packet without using RTS/CTS. The
default setting of 2347 (maximum length) disables RTS
Threshold.
DTIM Interval Delivery Traffic Indication Message (DTIM) is also known
as Beacon Rate. The entry range is a value between 1
and 65535. A DTIM is a countdown variable that informs
clients of the next window for listening to broadcast and
multicast messages. When the AP has buffered
broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. AP
Clients hear the beacons and awaken to receive the
broadcast and multicast messa
g
es. The default is 1.
Beacon Interval The amount of time between beacon transmissions in
milliseconds. The default is 100 ms and the acceptable
range is 1 – 65535. The beacon transmissions identify
the presence of an access point. By default, network
devices passively scan all RF channels listening for
beacons coming from access points. Before a station
enters power save mode, the station needs the beacon
interval to know when to wake up to receive the beacon
(and learn whether there are buffered frames at the
access point).
Global Max Clients The maximum number of clients that can connect to the
router.
Xpress TM Te c hn ol o gy Xpress Technology is compliant with draft specifications of
two planned wireless industry standards.
Transmit Power Set the power output (by percenta
g
e) as desired.
WMM (Wi-Fi
Multimedia)

WMM No
Acknowledgement
Refers to the acknowledge policy used at the MAC level.
Enabling no Acknowledgement can result in more efficient
throughput but higher error rates in a noisy Radio
Frequency (RF) environment.

contrast to static packet filtering which only examines a packet based on the
information in the packet header.
DENIAL OF SERVICE ATTACK
Is an incident in which a user or organization is deprived of the services of a
resource they would normally expect to have. Various DoS attacks the device can
withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf
Attack, and Tear Drop.
TCP/IP/PORT/INTERFACE FILTER
These rules help in the filtering of traffic at the Network layer (i.e. Layer 3).
When a Routing interface is created, Enable Firewall must be checked.
Navigate to Advanced Setup ÆSecurity ÆIP Filtering.
OUTGOING IP FILTER
Helps in setting rules to DROP packets from the LAN interface. By default, if the
Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more
filters, specific packet types coming from the LAN can be dropped.
Example 1:Filter Name : Out_Filter1
Protocol : TCP
Source IP address : 192.168.1.45
Source Subnet Mask : 255.255.255.0
Source Port : 80

Address/Subnet Mask 210.168.219.45/16 and a source port in the range of
5060 to 6060, destined to 192.168.1.45/24 and a destination port in the range
of 6060 to 7070. All other incoming packets on this interface are DROPPED.
MAC LAYER FILTER
These rules help in the filtering of Layer 2 traffic. MAC Filtering is only effective in
Bridge mode. After a Bridge mode connection is created, navigate to Advanced
Setup ÆSecurity ÆMAC Filtering in the WUI.
Example 1:Global Policy : Forwarded
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : NA
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule drops all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78:90 irrespective of its Source MAC
Address. All other frames on this interface are forwarded.
Example 2:Global Policy : Blocked
Protocol Type : PPPoE
Dest. MAC Address : 00:12:34:56:78:90
Source MAC Address : 00:34:12:78:90:56
Src. Interface : eth1
Dest. Interface : eth2
Addition of this rule forwards all PPPoE frames going from eth1 to eth2 with a
Destination MAC Address of 00:12:34:56:78 and Source MAC Address of
00:34:12:78:90:56. All other frames on this interface are dropped.

Appendix E- Connection Setup
Creating a WAN connection is a two-stage process.
1-Setup a Layer 2 Interface (ATM, PTM or Ethernet).
2-Add a WAN connection to the Layer 2 Interface.
The following sections describe each stage in turn.
E1 ~ Layer 2 Interfaces
Every layer2 interface operates in Multi-Service Connection (VLAN MUX) mode,
which supports multiple connections over a single interface. Note that PPPoA and
IPoA connection types are not supported for Ethernet WAN interfaces. After adding
WAN connections to an interface, you must also create an Interface Group to
connect LAN/WAN interfaces.
E1.1 ATM Interfaces
Follow these procedures to configure an ATM interface.
NOTE: The VR-3031u supports up to 16 ATM interfaces.
STEP 1: Go to Basic Setup ÆWAN Setup ÆSelect ATM Interface from the

dependent on the particular requirements of the ISP. The user name can be a
maximum of 256 characters and the password a maximum of 32 characters in
length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
153
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
DIAL ON DEMAND
The VR-3031u can be configured to disconnect if there is no activity for a period of
time by selecting the Dial on demand checkbox ;. You must also enter an
inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
x Allows only one PC on the LAN.
x Disables NAT and Firewall.
x The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
x The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
x The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
x The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox ;. The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox ;should not be selected to free up system
resources for better performance.
ENABLE FIREWALL
If this checkbox ;is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox ;
should not be selected to free up system resources for better performance.
USE STATIC IPv4 ADDRESS
Unless your service provider specially requires it, do not select this checkbox ;. If
selected, enter the static IP address in the IPv4 Address field.
Don’t forget to adjust the IP configuration to Static IP Mode as described in section
3.2.
154
FIXED MTU

the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS
(This option is hidden when PPP IP Extension is enabled)
When Enabled, this creates local PPPoE connections to the WAN side. Enable this
option only if all LAN-side devices are running PPPoE clients, otherwise disable it.
The VR-3031u supports pass-through PPPoE sessions from the LAN side while
simultaneously running a PPPoE client from non-PPPoE LAN devices.
ENABLE IGMP MULTICAST PROXY
Tick the checkbox ;to enable Internet Group Membership Protocol (IGMP)
multicast. This protocol is used by IPv4 hosts to report their multicast group
memberships to any neighboring multicast routers.
